PRINCIPAL INVESTMENT STRATEGIES

DIVERSIFICATION STATUS

Each Portfolio and Fund (except the SPDR SSgA Ultra Short Term Bond ETF, SSgA Ultra Short Term Bond Portfolio, SPDR SSgA Risk Aware ETF and State Street Risk Aware Portfolio) is classified as a “diversified” investment company under the 1940 Act. Under the 1940 Act, a diversified investment company, as to 75% of its total assets, may not purchase securities of any issuer (other than securities issued or guaranteed by the U.S. government, its agents or instrumentalities or securities of other investment companies) if, as a result, more than 5% of its total assets would be invested in the securities of such issuer, or more than 10% of the issuer’s outstanding voting securities would be held by the investment company.

The SPDR SSgA Ultra Short Term Bond ETF, SSgA Ultra Short Term Bond Portfolio, SPDR SSgA Risk Aware ETF and State Street Risk Aware Portfolio are each classified as a non-diversified investment company under the 1940 Act. A “non-diversified” classification means that each Portfolio or Fund is not limited by the 1940 Act with regard to the percentage of its assets that may be

invested in the securities of a single issuer. This means that each Portfolio or Fund may invest a greater portion of its assets in the securities of a single issuer than a diversified fund. This may have an adverse effect on a Portfolio or Fund’s performance or subject a Portfolio or Fund’s Shares to greater price volatility than more diversified investment companies.

Each Portfolio and each corresponding Fund intend to maintain a level of diversification and otherwise conduct their operations so as to enable the Fund to qualify for treatment as a “regulated investment company” for purposes of the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”), and to relieve the Fund of any liability for federal income tax to the extent that its earnings are distributed to shareholders. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of the Portfolios and may make it less likely that the Portfolios and Funds will meet their investment objectives.

CONCENTRATION

The Portfolios and Funds do not intend to concentrate their investments in any particular industry. The Portfolios and Funds (except the Blackstone / GSO Senior Loan Portfolio) look to the Global Industry Classification Standard Level 3 (Industries) in making industry determinations. The Blackstone / GSO Senior Loan portfolio looks to S&P Industry Classifications in making industry determinations.

PREFERRED SECURITIES

Each Portfolio may invest in preferred securities. Preferred securities pay fixed or adjustable rate dividends to investors, and have “preference” over common stock in the payment of dividends and the liquidation of a company’s assets. This means that a company must pay dividends on preferred stock before paying any dividends on its common stock. In order to be payable, distributions on preferred securities must be declared by the issuer’s board of directors. Income payments on typical preferred securities currently outstanding are cumulative, causing dividends and distributions to accrue even if not declared by the board of directors or otherwise made payable. There is no assurance that dividends or distributions on the preferred securities in which a Portfolio invests will be declared or otherwise made payable.

The market value of preferred securities may be affected by favorable and unfavorable changes impacting companies in the utilities and financial services sectors, which are prominent issuers of preferred securities, and by actual and anticipated changes in tax laws.

Because the claim on an issuer’s earnings represented by preferred securities may become onerous when interest rates fall below the rate payable on such securities, the issuer may redeem the securities. Thus, in declining interest rate environments in particular, a Portfolio’s holdings of higher rate-paying fixed rate preferred securities may be reduced and a Portfolio would be unable to acquire securities paying comparable rates with the redemption proceeds.

CONVERTIBLE SECURITIES

Each Portfolio may invest in convertible securities. Convertible securities are bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio. A convertible security may also be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. If a convertible security held by a Portfolio is called for redemption or conversion, the Portfolio could be required to tender it for redemption, convert it into the underlying common stock, or sell it to a third party.

Convertible securities generally have less potential for gain or loss than common stocks. Convertible securities generally provide yields higher than the underlying common stocks, but generally lower than comparable non-convertible securities. Because of this higher yield, convertible securities generally sell at a price above their “conversion value,” which is the current market value of the stock to be received upon conversion. The difference between this conversion value and the price of convertible securities will vary over time depending on changes in the value of the underlying common stocks and interest rates. When the underlying common stocks decline in value, convertible securities will tend not to decline to the same extent because of the interest or dividend payments and the repayment of principal at maturity for certain types of convertible securities. However, securities that are convertible other than at the option of the holder generally do not limit the potential for loss to the same extent as securities convertible at the option of the holder. When the underlying common stocks rise in value, the value of convertible securities may also be expected to increase. At the same time, however, the difference between the market value of convertible securities and their conversion value will narrow, which means that the value of convertible securities will generally not increase to the same extent as the value of the underlying common stocks. Because convertible securities may also be interest-rate sensitive, their value may increase as interest rates fall and decrease as interest rates rise. Convertible securities are also subject to credit risk, and are often lower-quality securities.

BONDS

Each Portfolio may invest in bonds. A bond is an interest-bearing security issued by a company, governmental unit or, in some cases, a non-U.S. entity. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond’s face value) periodically or on a specified maturity date; provided, however, a zero coupon bond pays no interest to its holder during its life. The value of a zero coupon bond to a fund consists of the difference between such bond’s face value at the time of maturity and the price for which it was acquired, which may be an amount significantly less than its face value (sometimes referred to as a “deep discount” price).

Table of Contents

An issuer may have the right to redeem or “call” a bond before maturity, in which case the investor may have to reinvest the proceeds at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed rate bond’s yield (income as a percent of the bond’s current value) may differ from its coupon rate as its value rises or falls. Fixed rate bonds generally are also subject to inflation risk, which is the risk that the value of the bond or income from the bond will be worth less in the future as inflation decreases the value of money. This could mean that, as inflation increases, the “real” value of the assets of a fund holding fixed rate bonds can decline, as can the value of the fund’s distributions. Other types of bonds bear income at an interest rate that is adjusted periodically. Because of their adjustable interest rates, the value of “floating-rate” or “variable-rate” bonds fluctuates much less in response to market interest rate movements than the value of fixed rate bonds. A Portfolio may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on a corporation’s earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (also backed by specified collateral).

In addition, each Portfolio may invest in corporate bonds. The investment return of corporate bonds reflects interest on the bond and changes in the market value of the bond. The market value of a corporate bond may be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the market place. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by such a security.

SENIOR LOANS

The Blackstone / GSO Senior Loan Portfolio invests primarily in Senior Loans. Senior Loans consist generally of obligations of companies and other entities (collectively, “borrowers”) incurred for the purpose of reorganizing the assets and liabilities of a borrower; acquiring another company; taking over control of a company (leveraged buyout); temporary refinancing; or financing internal growth or other general business purposes. Senior Loans are often obligations of borrowers who have incurred a significant percentage of debt compared to their total assets and thus are highly leveraged. The Portfolio and Fund do not treat the banks originating or acting as agents for the lenders, or granting or acting as intermediary in participation interests, in loans held by the Portfolio as the issuers of such loans.

Senior Loans may be acquired by direct investment as a lender at the inception of the loan or by assignment of a portion of a loan previously made to a different lender or by purchase of a participation interest. If the Portfolio makes a direct investment in a Senior Loan as one of the lenders, it generally acquires the loan at or below par. This means the Portfolio receives a return at or above the full interest rate for the loan. If the Portfolio acquires its interest in Senior Loans in the secondary market or acquires a participation interest, the loans may be purchased or sold above, at, or below par, which can result in a yield that is below, equal to, or above the stated interest rate of the loan. At times, the Portfolio may be able to invest in Senior Loans only through assignments or participations.

When the Portfolio is a purchaser of an assignment, it succeeds to all the rights and obligations under the loan agreement of the assigning lender and becomes a lender under the loan agreement with the same rights and obligations as the assigning lender. These rights include the ability to vote along with the other lenders on such matters as enforcing the terms of the loan agreement ( e.g. , declaring defaults, initiating collection actions, etc.). Taking such actions typically requires at least a vote of the lenders holding a majority of the investment in the loan and may require a vote by lenders holding two-thirds or more of the investment in the loan. Because the Portfolio usually does not hold a majority of the investment in any loan, it will not be able by itself to control decisions that require a vote by the lenders.

The Fund may, but will not typically, invest in Senior Loans through participations. A participation interest represents a fractional interest in a loan held by the lender selling the Portfolio the participation interest. In the case of participations, the Portfolio will not have any direct contractual relationship with the borrower, the Portfolio’s rights to consent to modifications of the loan are limited and it is dependent upon the participating lender to enforce the Portfolio’s rights upon a default. The Portfolio will have the right to receive payments of principal, interest, and any fees to which it is entitled only from the lender selling the participation and only upon receipt by the lender of the payments from the borrower. The Fund will only purchase participations from lenders with credit ratings of Baa3 or higher by Moody’s or BBB- or higher by S&P or Fitch, or a comparable rating by another nationally recognized rating agency.

The Portfolio may be affected by the credit of both the agent and the lender from whom the Portfolio acquires a participation interest. These credit risks may include delay in receiving payments of principal and interest paid by the borrower to the agent or by the agent to the lender or offsets against payments received from the borrower. In the event of the borrower’s bankruptcy, the borrower’s obligation to repay the loan may be subject to defenses that the borrower can assert as a result of improper conduct by the agent.

Historically, the amount of public information available about a specific Senior Loan has been less extensive than if the loan were registered or exchange-traded.

The loans in which the Portfolio will invest will, in most instances, be Senior Loans, which are secured and senior to other indebtedness of the borrower. Each Senior Loan will generally be secured by collateral such as accounts receivable, inventory, equipment, real estate, intangible assets such as trademarks, copyrights and patents, and securities of subsidiaries or affiliates. The value of the collateral generally will be determined by reference to financial statements of the borrower, by an independent appraisal, by obtaining the market value of such collateral, in the case of cash or securities if readily ascertainable, or by other customary valuation techniques considered appropriate by the Adviser. The value of collateral may decline after the Portfolio’s investment, and collateral may be difficult to sell in the event of default. Consequently, the Portfolio may not receive all the payments to which it is entitled. By virtue of their senior position and collateral, Senior Loans typically provide lenders with the first right to cash flows or proceeds from the sale of a borrower’s collateral if the borrower becomes insolvent (subject to the limitations of bankruptcy law, which may provide higher priority to certain claims such as employee salaries, employee pensions, and taxes). This means Senior Loans are generally repaid before unsecured bank loans, corporate bonds, subordinated debt, trade creditors, and preferred or common stockholders. To the extent that the Portfolio invests in unsecured loans, if the borrower defaults on such loan, there is no specific collateral on which the lender can foreclose. If the borrower defaults on a subordinated loan, the collateral may not be sufficient to cover both the senior and subordinated loans.

Senior Loans will usually require, in addition to scheduled payments of interest and principal, the prepayment of the Senior Loan from free cash flow, as further described below. The degree to which borrowers prepay Senior Loans, whether as a contractual requirement or at their election, may be affected by general business conditions, the financial condition of the borrower and competitive conditions among loan investors, among others. As such, prepayments cannot be predicted with accuracy. Recent market conditions, including falling default rates among others, have led to increased prepayment frequency and loan renegotiations. These renegotiations are often on terms more favorable to borrowers. Upon a prepayment, either in part or in full, the actual outstanding debt on which the Portfolio derives interest income will be reduced. However, the Portfolio may receive a prepayment penalty fee assessed against the prepaying borrower.

Senior Loans typically pay interest at least quarterly at rates which equal a fixed percentage spread over a base rate such as the London Interbank Offered Rate (“LIBOR”). For example, if LIBOR were 0.3% and the borrower was paying a fixed spread of 2.50%, the total interest rate paid by the borrower would be 2.80%. Additionally, many Senior Loans also have a minimum base rate, or floor, which will be used if the actual base rate is below this minimum base rate. This measure is designed to ensure lenders receive a minimum interest rate in periods of low interest rates. By illustration, if LIBOR were 0.3% and the borrower was paying a fixed spread of 2.50%, the total interest rate paid by the borrower would be 2.80%. However, if the same Senior Loan had a LIBOR floor of 1.50%, then 1.50% would be used as the base rate notwithstanding that LIBOR was currently at 0.3%, thereby making the interest rate paid the borrower 4.00% (1.50% LIBOR floor base rate plus 2.50% fixed spread). During periods when LIBOR is greater than the LIBOR floor, the LIBOR floor would have no impact on the interest rate paid by the borrower. Not all Senior Loans have LIBOR floors and this feature is a relatively recent invention which may not persist in future issuances of Senior Loans.

Although a base rate such as LIBOR can change every day, loan agreements for Senior Loans typically allow the borrower the ability to choose how often the base rate for its loan will reset. A single loan may have multiple reset periods at the same time, with each reset period applicable to a designated portion of the loan. Such reset periods can range from one day to one year, with most borrowers choosing monthly or quarterly reset periods. During periods of rising interest rates, borrowers will tend to choose longer reset periods, and during periods of declining interest rates, borrowers will tend to choose shorter reset periods. The fixed spread over the base rate on a Senior Loan typically does not change.

Senior Loans generally are arranged through private negotiations between a borrower and several financial institutions represented by an agent who is usually one of the originating lenders. In larger transactions, it is common to have several agents; however, generally only one such agent has primary responsibility for ongoing administration of a Senior Loan. Agents are typically paid fees by the borrower for their services.

The agent is primarily responsible for negotiating the loan agreement which establishes the terms and conditions of the Senior Loan and the rights of the borrower and the lenders. The agent also is responsible for monitoring collateral and for exercising remedies available to the lenders such as foreclosure upon collateral. The Sub-Adviser or its affiliates may from time to time borrow from financial institutions that act as agents for loans.

Loan agreements may provide for the termination of the agent’s agency status in the event that it fails to act as required under the relevant loan agreement, becomes insolvent, enters Federal Deposit Insurance Corporation (“FDIC”) receivership or, if not FDIC insured, enters into bankruptcy. Should such an agent, lender or assignor with respect to an assignment interpositioned between the Portfolio and the borrower become insolvent or enter FDIC receivership or bankruptcy, any interest in the Senior Loan of such person and any loan payment held by such person for the benefit of the Portfolio should not be included in such person’s or entity’s bankruptcy estate. If, however, any such amount were included in such person’s or entity’s bankruptcy estate, the Portfolio would incur certain costs and delays in realizing payment or could suffer a loss of principal or interest. In this event, the Portfolio and, therefore, the Fund could experience a decrease in the NAV.

Most borrowers pay their debts from cash flow generated by their businesses. If a borrower’s cash flow is insufficient to pay its debts, it may attempt to restructure its debts rather than sell collateral. Borrowers may try to restructure their debts by filing for protection under the federal bankruptcy laws or negotiating a work-out. If a borrower becomes involved in a bankruptcy proceeding, access to collateral may be limited by bankruptcy and other laws. Such action by a court could be based, for example, on a “fraudulent conveyance” claim to the effect that the borrower did not receive fair consideration for granting the security interest in the loan collateral to the Portfolio. If a court decides that access to collateral is limited or void, the Portfolio may not recover the full amount of principal and interest that is due.

A borrower must comply with certain restrictive covenants contained in the loan agreement. In addition to requiring the scheduled payment of principal and interest, these covenants may include restrictions on the payment of dividends and other distributions to the borrower’s shareholders, provisions requiring compliance with specific financial ratios, and limits on total indebtedness. The agreement may also require the prepayment of the loans from excess cash flow. A breach of a covenant that is not waived by the agent (or lenders directly) is normally an event of default, which provides the agent and lenders the right to call for repayment of the outstanding loan. The typical practice of an agent or a loan investor in relying exclusively or primarily on reports from the borrower to monitor the borrower’s compliance with covenants may involve a risk of fraud by the borrower.

In the process of buying, selling and holding Senior Loans, the Portfolio may receive and/or pay certain fees. These fees are in addition to interest payments received and may include facility fees, commitment fees, commissions and prepayment penalty fees. When the Portfolio buys or sells a Senior Loan it may pay a facility fee. On an ongoing basis, the Portfolio may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a Senior Loan. In certain circumstances, the Portfolio may receive a prepayment penalty fee upon prepayment of a Senior Loan. Other fees received by the Portfolio may include covenant waiver fees, covenant modification fees or other consent or amendment fees.

Notwithstanding its intention in certain situations to not receive material, non-public information with respect to its management of investments in Senior Loans, the Adviser and/or Sub-Adviser may from time to time come into possession of material, non-public information about the issuers of loans that may be held in the Portfolio’s portfolio. Possession of such information may in some instances occur despite the Adviser’s and/or Sub-Adviser’s efforts to avoid such possession, but in other instances the Adviser and/or Sub-Adviser may choose to receive such information (for example, in connection with participation in a creditors’ committee with respect to a financially distressed issuer). The Adviser’s and/or Sub-Adviser’s ability to trade in these Senior Loans for the account of the Portfolio could potentially be limited by its possession of such information. Such limitations on the Adviser’s and/or Sub-Adviser’s ability to trade could have an adverse effect on the Portfolio by, for example, preventing the Portfolio from selling a Senior Loan that is experiencing a material decline in value. In some instances, these trading restrictions could continue in effect for a substantial period of time.

The loan market, as represented by the S&P/LSTA (Loan Syndications and Trading Association) Leveraged Loan Index, experienced significant growth in terms of number and aggregate volume of loans outstanding since the inception of the index in 1997. In 1997, the total amount of loans in the market aggregated less than $10 billion. By April of 2000, it had grown to over $100 billion, and by July of 2007 the market had grown to over $500 billion. The size of the market peaked in November of 2008 at $594 billion. During this period, the demand for loans and the number of investors participating in the loan market also increased significantly.

Since 2008, the aggregate size of the market has contracted, characterized by limited new loan issuance and payoffs of outstanding loans. From the peak in 2008 through July 2010, the overall size of the loan market contracted by approximately 15%. The number of market participants also decreased during that period. There can be no assurance that the size of the loan market, and the number of participants, will return to earlier levels.

An increase in demand for Senior Loans may benefit the Portfolio by providing increased liquidity for such loans and higher sales prices, but it may also adversely affect the rate of interest payable on such loans acquired by the Portfolio and the rights provided to the Portfolio under the terms of the applicable loan agreement, and may increase the price of loans that the Portfolio wishes to purchase in the secondary market. A decrease in the demand for Senior Loans may adversely affect the price of loans in the Portfolio’s portfolio, which could cause the Portfolio’s and, therefore, the Fund’s net asset value to decline.

The Portfolio may acquire interests in Senior Loans which are designed to provide temporary or “bridge” financing to a borrower pending the sale of identified assets or the arrangement of longer-term loans or the issuance and sale of debt obligations. The Portfolio may also invest in Senior Loans of borrowers that have obtained bridge loans from other parties. A borrower’s use of bridge loans involves a risk that the borrower may be unable to locate permanent financing to replace the bridge loan, which may impair the borrower’s perceived creditworthiness. Bridge loans may have less liquidity than other Senior Loans that were issued to fund corporate purposes on a longer term basis.

Although not anticipated in the normal course, the Portfolio may occasionally acquire warrants and other equity securities as part of a unit combining a Senior Loan and equity securities of a borrower or its affiliates. The acquisition of such equity securities will only be

7

Table of Contents

incidental to the Portfolio’s purchase of a Senior Loan. The Portfolio may also acquire equity securities or credit securities (including non-dollar denominated equity or credit securities) issued in exchange for a Senior Loan or issued in connection with the debt restructuring or reorganization of a Borrower, or if such acquisition, in the judgment of the Adviser may enhance the value of a Senior Loan or would otherwise be consistent with the Portfolio’s investment policies. Such warrants and equity securities will typically have limited value and there is no assurance that such securities will ever obtain value.

OTHER LOANS

The Blackstone / GSO Senior Loan Portfolio may invest in secured loans that are not first lien and loans that are unsecured. These loans have the same characteristics as Senior Loans except that such loans are not first in priority of repayment and/or are not secured by collateral. Accordingly, the risks associated with these loans are higher than the risks for loans with first priority over the collateral. Because these loans are lower in priority and/or unsecured, they are subject to the additional risk that the cash flow of the borrower may be insufficient to meet scheduled payments after giving effect to the secured obligations of the borrower. In the event of default on such a loan, the first priority lien holder has first claim to the underlying collateral of the loan. It is possible that no value would remain for the holders of secured loans that are not first lien and loans that are unsecured and therefore result in a loss of investment to the Portfolio.

Secured loans that are not first lien and loans that are unsecured generally have greater price volatility than Senior Loans and may be less liquid. There is also a possibility that originators will not be able to sell participations in these loans, which would create greater credit risk exposure for the holders of such loans. Secured loans that are not first lien and loans that are unsecured share the same risks as other below investment grade instruments.

VARIABLE AND FLOATING RATE SECURITIES

The SPDR SSgA Ultra Short Term Bond Portfolio and State Street Risk Aware Portfolio may each invest in variable and floating rate securities. Variable rate securities are instruments issued or guaranteed by entities such as (1) US government, or an agency or instrumentality thereof, (2) corporations, (3) financial institutions, (4) insurance companies or (5) trusts that have a rate of interest subject to adjustment at regular intervals but less frequently than annually. A variable rate security provides for the automatic establishment of a new interest rate on set dates. Variable rate obligations whose interest is readjusted no less frequently than annually will be deemed to have a maturity equal to the period remaining until the next readjustment of the interest rate. Each Portfolio may also purchase floating rate securities. A floating rate security provides for the automatic adjustment of its interest rate whenever a specified interest rate changes. Interest rates on these securities are ordinarily tied to, and are a percentage of, a widely recognized interest rate, such as the yield on 90-day US Treasury bills or the prime rate of a specified bank. These rates may change as often as twice daily. Generally, changes in interest rates will have a smaller effect on the market value of variable and fixed rate floating rate securities than on the market value of comparable fixed rate fixed income obligations. Thus, investing in variable and fixed rate floating rate securities generally allows less opportunity for capital appreciation and depreciation than investing in comparable fixed rate fixed income securities.

COMMERCIAL PAPER

Each Portfolio may invest in commercial paper. Commercial paper consists of short-term, promissory notes issued by banks, corporations and other entities to finance short-term credit needs. These securities generally are discounted but sometimes may be interest bearing.

OTHER SHORT-TERM INSTRUMENTS

In addition to repurchase agreements, each Portfolio may invest in short-term instruments, including money market instruments, (including money market funds advised by the Adviser), cash and cash equivalents, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include but are not limited to: (i) shares of money market funds (including those advised by the Adviser); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed time deposits and other obligations of U.S. and foreign banks (including foreign branches) and similar institutions; (iv) commercial paper rated at the date of purchase “Prime-1” by Moody’s Investor’s Service (“Moody’s”) or “A-1” by Standard & Poor’s (“S&P”), or if unrated, of comparable quality as determined by the Adviser; (v) non-convertible corporate debt securities ( e.g. , bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that satisfy the rating requirements set forth in Rule 2a-7 under the 1940 Act; and (vi) short-term U.S. dollar-denominated obligations of foreign banks (including U.S. branches) that, in the opinion of the Adviser, are of comparable quality to obligations of U.S. banks which may be purchased by a Portfolio. Any of these instruments may be purchased on a current or a forward-settled basis. Money market instruments also include shares of money market funds. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

COLLATERALIZED LOAN OBLIGATIONS (“CLOs”)

Each Portfolio (except the Blackstone / GSO Senior Loan Portfolio) may invest in CLOs. A CLO is a financing company (generally called a Special Purpose Vehicle or “SPV”), created to reapportion the risk and return characteristics of a pool of assets. While the assets underlying CLOs are typically Senior Loans, the assets may also include (i) unsecured loans, (ii) other debt securities that are rated below investment grade, (iii) debt tranches of other CLOs and (iv) equity securities incidental to investments in Senior Loans. When investing in CLOs, a Portfolio will not invest in equity tranches, which are the lowest tranche. However, a Portfolio may invest in lower debt tranches of CLOs, which typically experience a lower recovery, greater risk of loss or deferral or non-payment of interest than more senior debt tranches of the CLO. In addition, a Portfolio intends to invest in CLOs consisting primarily of individual Senior Loans of borrowers and not repackaged CLO obligations from other high risk pools. The underlying Senior Loans purchased by CLOs are generally performing at the time of purchase but may become non-performing, distressed or defaulted. CLOs with underlying assets of non-performing, distressed or defaulted loans are not contemplated to comprise a significant portion of a Portfolio’s investments in CLOs. The key feature of the CLO structure is the prioritization of the cash flows from a pool of debt securities among the several classes of the CLO. The SPV is a company founded solely for the purpose of securitizing payment claims arising out of this diversified asset pool. On this basis, marketable securities are issued by the SPV which, due to the diversification of the underlying risk, generally represent a lower level of risk than the original assets. The redemption of the securities issued by the SPV typically takes place at maturity out of the cash flow generated by the collected claims.

Holders of CLOs bear risks of the underlying investments, index or reference obligation and are subject to counterparty risk.

A Portfolio may have the right to receive payments only from the CLOs, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain CLOs enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in CLOs generally pay their share of the CLO’s administrative and other expenses. Although it is difficult to predict whether the prices of indices and securities underlying a CLO will rise or fall, these prices (and, therefore, the prices of CLOs) will be influenced by the same types of political and economic events that affect issuers of securities and capital markets generally. If the issuer of a CLO uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining short-term financing, which may adversely affect the value of the CLOs owned by a Portfolio.

Certain CLOs may be thinly traded or have a limited trading market. CLOs are typically privately offered and sold. As a result, investments in CLOs may be characterized by a Portfolio as illiquid securities. In addition to the general risks associated with debt securities discussed herein, CLOs carry additional risks, including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the investments in CLOs are subordinate to other classes or tranches thereof; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

HIGH YIELD SECURITIES

Each Portfolio may invest in high yield debt securities. Investment in high yield securities generally provides greater income and increased opportunity for capital appreciation than investments in higher quality securities, but they also typically entail greater price volatility and credit risk. These high yield securities are regarded as predominantly speculative with respect to the issuer’s continuing ability to meet principal and interest payments. Analysis of the creditworthiness of issuers of debt securities that are high yield may be more complex than for issuers of higher quality debt securities. In addition, high yield securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) firms, which are generally less able than more financially stable firms to make scheduled payments of interest and principal. The risks posed by securities issued under such circumstances are substantial.

Investing in high yield debt securities involves risks that are greater than the risks of investing in higher quality debt securities. These risks include: (i) changes in credit status, including weaker overall credit conditions of issuers and risks of default; (ii) industry, market and economic risk; and (iii) greater price variability and credit risks of certain high yield securities such as zero coupon and payment-in-kind securities. While these risks provide the opportunity for maximizing return over time, they may result in greater volatility of the value of a Portfolio and, therefore, a Fund than a fund that invests in higher-rated securities.

Furthermore, the value of high yield securities may be more susceptible to real or perceived adverse economic, company or industry conditions than is the case for higher quality securities. The market values of certain of these lower-rated and unrated debt securities tend to reflect individual corporate developments to a greater extent than do higher-rated securities which react primarily to fluctuations in the general level of interest rates, and tend to be more sensitive to economic conditions than are higher-rated securities. Adverse market, credit or economic conditions could make it difficult at certain times to sell certain high yield securities held by a Portfolio.

The secondary market on which high yield securities are traded may be less liquid than the market for higher grade securities. Less liquidity in the secondary trading market could adversely affect the price at which a Portfolio could sell a high yield security, and could adversely affect the daily net asset value per share of a Portfolio and, therefore, a Fund. When secondary markets for high yield securities are less liquid than the market for higher grade securities, it may be more difficult to value the securities because there is less reliable, objective data available.

Table of Contents

The use of credit ratings as a principal method of selecting high yield securities can involve certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield securities. Also, credit rating agencies may fail to change credit ratings in a timely fashion to reflect events since the security was last rated.

SOVEREIGN DEBT OBLIGATIONS

Each Portfolio (except the Blackstone / GSO Senior Loan Portfolio) may invest in sovereign debt. Sovereign debt obligations are issued or guaranteed by foreign governments or their agencies. Sovereign debt may be in the form of conventional securities or other types of debt instruments such as loans or loan participations. Governmental entities responsible for repayment of the debt may be unable or unwilling to repay principal and pay interest when due, and may require renegotiation or reschedule of debt payments. In addition, prospects for repayment of principal and payment of interest may depend on political as well as economic factors. Although some sovereign debt, such as Brady Bonds, is collateralized by U.S. government securities, repayment of principal and payment of interest is not guaranteed by the U.S. government.

U.S. GOVERNMENT OBLIGATIONS

Each Portfolio may invest in U.S. government obligations. U.S. government obligations are a type of bond. U.S. government obligations include securities issued or guaranteed as to principal and interest by the U.S. government, its agencies or instrumentalities.

One type of U.S. government obligation, U.S. Treasury obligations, are backed by the full faith and credit of the U.S. Treasury and differ only in their interest rates, maturities, and times of issuance. U.S. Treasury bills have initial maturities of one-year or less; U.S. Treasury notes have initial maturities of one to ten years; and U.S. Treasury bonds generally have initial maturities of greater than ten years.

Other U.S. government obligations are issued or guaranteed by agencies or instrumentalities of the U.S. government including, but not limited to, Federal National Mortgage Association (“Fannie Mae”), the Government National Mortgage Association (“Ginnie Mae”), the Small Business Administration, the Federal Farm Credit Administration, the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal Home Loan Banks (“FHLB”), Banks for Cooperatives (including the Central Bank for Cooperatives), the Federal Land Banks, the Federal Intermediate Credit Banks, the Tennessee Valley Authority, the Export-Import Bank of the United States, the Commodity Credit Corporation, the Federal Financing Bank, the Student Loan Marketing Association, the National Credit Union Administration and the Federal Agricultural Mortgage Corporation (Farmer Mac). Some obligations issued or guaranteed by U.S. government agencies and instrumentalities, including, for example, Ginnie Mae pass-through certificates, are supported by the full faith and credit of the U.S. Treasury. Other obligations issued by or guaranteed by federal agencies, such as those securities issued by Fannie Mae, are supported by the discretionary authority of the U.S. government to purchase certain obligations of the federal agency, while other obligations issued by or guaranteed by federal agencies, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the U.S. Treasury, while the U.S. government provides financial support to such U.S. government-sponsored federal agencies, no assurance can be given that the U.S. government will always do so, since the U.S. government is not so obligated by law.

On September 7, 2008, the U.S. Treasury announced a federal takeover of Fannie Mae and Freddie Mac, placing the two federal instrumentalities in conservatorship. Under the takeover, the U.S. Treasury agreed to acquire $1 billion of senior preferred stock of each instrumentality and obtained warrants for the purchase of common stock of each instrumentality (the “Senior Preferred Stock Purchase Agreement” or “Agreement”). Under the Agreement, the U.S. Treasury pledged to provide up to $200 billion per instrumentality as needed, including the contribution of cash capital to the instrumentalities in the event their liabilities exceed their assets. This was intended to ensure that the instrumentalities maintain a positive net worth and meet their financial obligations, preventing mandatory triggering of receivership. On December 24, 2009, the U.S. Treasury announced that it was amending the Agreement to allow the $200 billion cap on the U.S. Treasury’s funding commitment to increase as necessary to accommodate any cumulative reduction in net worth over the next three years. As a result of this Agreement, the investments of holders, including applicable Portfolios, of mortgage-backed securities and other obligations issued by Fannie Mae and Freddie Mac are protected to the extent of such commitment.

VARIABLE RATE DEMAND OBLIGATIONS

Each Portfolio may invest in Variable Rate Demand Obligations (VRDO). VRDOs are short-term tax exempt fixed income instruments whose yield is reset on a periodic basis. VRDO securities tend to be issued with long maturities of up to 30 or 40 years; however, they are considered short-term instruments because they include a put feature which coincides with the periodic yield reset. For example, a VRDO whose yield resets weekly will have a put feature that is exercisable upon seven days notice. VRDOs are put back to a bank or other entity that serves as a liquidity provider, who then tries to resell the VRDOs or, if unable to resell, holds them in its own inventory. VRDOs are generally supported by either a Letter of Credit or a Stand-by Bond Purchase Agreement to provide credit enhancement.

INFLATION-PROTECTED OBLIGATIONS

Each Portfolio may invest in inflation-protected public obligations, commonly known as “TIPS,” of the U.S. Treasury, as well as inflation-protected public obligations of major governments and emerging market countries, excluding the United States. An inflation-protected public obligation is a type of security issued by a government that is designed to provide inflation protection to investors. Inflation-protected public obligations are income-generating instruments whose interest and principal payments are adjusted for inflation—a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, such as the Consumer Price Index. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises or falls, both the principal value and the interest payments will increase or decrease. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

MORTGAGE PASS-THROUGH SECURITIES

Each Portfolio may invest a substantial portion of its assets in U.S. agency mortgage pass-through securities. The term “U.S. agency mortgage pass-through security” refers to a category of pass-through securities backed by pools of mortgages and issued by one of several U.S. government-sponsored enterprises: the Ginnie Mae, Fannie Mae or Freddie Mac. In the basic mortgage pass-through structure, mortgages with similar issuer, term and coupon characteristics are collected and aggregated into a “pool” consisting of multiple mortgage loans. The pool is assigned a CUSIP number and undivided interests in the pool are traded and sold as pass-through securities. The holder of the security is entitled to a pro rata share of principal and interest payments (including unscheduled prepayments) from the pool of mortgage loans.

An investment in a specific pool of pass-through securities requires an analysis of the specific prepayment risk of mortgages within the covered pool (since mortgagors typically have the option to prepay their loans). The level of prepayments on a pool of mortgage securities is difficult to predict and can impact the subsequent cash flows and value of the mortgage pool. In addition, when trading specific mortgage pools, precise execution, delivery and settlement arrangements must be negotiated for each transaction. These factors combine to make trading in mortgage pools somewhat cumbersome.

For the foregoing and other reasons, the Portfolios seek to obtain exposure to U.S. agency mortgage pass-through securities primarily through the use of “to-be-announced” or “TBA transactions.” “TBA” refers to a commonly used mechanism for the forward settlement of U.S. agency mortgage pass-through securities, and not to a separate type of mortgage-backed security. Most transactions in mortgage pass-through securities occur through the use of TBA transactions. TBA transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA transaction, the buyer and seller decide on general trade parameters, such as agency, settlement date, par amount, and price. The actual pools delivered generally are determined two days prior to settlement date. Each Portfolio intends to use TBA transactions in several ways. For example, each Portfolio expects that it will regularly enter into TBA agreements and “roll over” such agreements prior to the settlement date stipulated in such agreements. This type of TBA transaction is sometimes known as a “TBA roll.” In a “TBA roll” a Portfolio generally will sell the obligation to purchase the pools stipulated in the TBA agreement prior to the stipulated settlement date and will enter into a new TBA agreement for future delivery of pools of mortgage pass-through securities. In addition, a Portfolio may enter into TBA agreements and settle such transactions on the stipulated settlement date by accepting actual receipt or delivery of the pools of mortgage pass-through securities stipulated in the TBA agreement.

Default by or bankruptcy of a counterparty to a TBA transaction would expose a Portfolio to possible loss because of adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA transaction. To minimize this risk, a Portfolio will enter into TBA transactions only with established counterparties (such as major broker-dealers) and the Adviser will monitor the creditworthiness of such counterparties. In addition, a Portfolio may accept assignments of TBA transactions from Authorized Participants (as defined below) from time to time. A Portfolio’s use of “TBA rolls” may cause the Portfolio to experience higher portfolio turnover, higher transaction costs and to pay higher capital gain distributions to shareholders (which may be taxable) than other funds.

The Portfolios intend to invest cash pending settlement of any TBA transactions in money market instruments, repurchase agreements, commercial paper (including asset-backed commercial paper) or other high-quality, liquid short-term instruments, which may include money market funds affiliated with the Adviser.

ASSET-BACKED AND COMMERCIAL MORTGAGE-BACKED SECURITIES

The Portfolios may invest in asset-backed and commercial mortgaged-backed securities. Asset-backed securities are securities backed by installment contracts, credit-card receivables or other assets. Commercial mortgage-backed securities are securities backed by commercial real estate properties. Mortgage-backed securities are issued by the U.S. government or a government-sponsored enterprise, or by a private entity. Depending on the issuer, mortgage-backed securities may or may not be guaranteed. Both asset-backed and commercial mortgage-backed securities represent interests in “pools” of assets in which payments of both interest and

11

Table of Contents

principal on the securities are made on a regular basis. The payments are, in effect, “passed through” to the holder of the securities (net of any fees paid to the issuer or guarantor of the securities). The average life of asset-backed and commercial mortgage-backed securities varies with the maturities of the underlying instruments and, as a result of prepayments, can often be less than the original maturity of the assets underlying the securities. For this and other reasons, an asset-backed and commercial mortgage-backed security’s stated maturity may be shortened, and the security’s total return may be difficult to predict precisely.

RESTRICTED SECURITIES

SPDR SSgA Ultra Short Term Bond Portfolio may invest in restricted securities. Restricted Securities are securities that are not registered under the Securities Act, but which can be offered and sold to “qualified institutional buyers” under Rule 144A under the Securities Act. Institutional markets for restricted securities have developed as a result of the promulgation of Rule 144A under the Securities Act, which provides a “safe harbor” from Securities Act registration requirements for qualifying sales to institutional investors. When Rule 144A restricted securities present an attractive investment opportunity and meet other selection criteria, the Portfolio may make such investments whether or not such securities are “illiquid” depending on the market that exists for the particular security. The Board has delegated the responsibility for determining the liquidity of Rule 144A restricted securities that the Portfolio may invest in to the Adviser. In reaching liquidity decisions, the Adviser may consider the following factors: the frequency of trades and quotes for the security; the number of dealers wishing to purchase or sell the security and the number of other potential purchasers; dealer undertakings to make a market in the security; and the nature of the security and the nature of the marketplace in which it trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer).

FOREIGN CURRENCY TRANSACTIONS

Each Portfolio (except the Blackstone / GSO Senior Loan Portfolio) may conduct foreign currency transactions on a spot ( i.e. , cash) or forward basis ( i.e. , by entering into forward contracts to purchase or sell foreign currencies). Although foreign exchange dealers generally do not charge a fee for such conversions, they do realize a profit based on the difference between the prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency at one rate, while offering a lesser rate of exchange should the counterparty desire to resell that currency to the dealer. Forward contracts are customized transactions that generally require a specific amount of a currency to be delivered at a specific exchange rate on a specific date or range of dates in the future although a Portfolio may also enter into non-deliverable currency forward contracts (“NDFs”) that contractually require the netting of the parties’ liabilities. Forwards, including NDFs, can have substantial price volatility. Forward contracts are generally traded in an interbank market directly between currency traders (usually large commercial banks) and their customers. The parties to a forward contract may agree to offset or terminate the contract before its maturity, or may hold the contract to maturity and complete the contemplated currency exchange. At the discretion of the Adviser, the Portfolios may enter into forward currency exchange contracts for hedging purposes to help reduce the risks and volatility caused by changes in foreign currency exchange rates, or to gain exposure to certain currencies. When used for hedging purposes, they tend to limit any potential gain that may be realized if the value of the Portfolio’s foreign holdings increases because of currency fluctuations.

BUILD AMERICA BONDS

Each Portfolio may invest a portion of its assets in Build America Bonds. Build America Bonds offer an alternative form of financing to state and local governments whose primary means for accessing the capital markets has historically been through the issuance of tax-free municipal bonds. The Build America Bond program allows state and local governments to issue taxable bonds for capital projects and to receive a direct federal subsidy payment from the Treasury Department for a portion of their borrowing costs. There are two general types of Build America Bonds. The first type of Build America Bond provides a federal subsidy through federal tax credits to investors in the bonds in an amount equal to 35 percent of the total coupon interest payable by the issuer on taxable governmental bonds (net of the tax credit), which represents a federal subsidy to the state or local governmental issuer equal to approximately 25 percent of the total return to the investor (including the coupon interest paid by the issuer and the tax credit). The second type of Build America Bond provides a federal subsidy through a refundable tax credit paid to state or local governmental issuers by the Treasury Department and the IRS in an amount equal to 35 percent (or 45 percent in the case of Recovery Zone Economic Development Bonds) of the total coupon interest payable to investors in these taxable bonds.

Issuance of Build America Bonds ceased on December 31, 2010. The Build America Bonds outstanding continue to be eligible for the federal interest rate subsidy, which continues for the life of the Build America Bonds; however, no bonds issued following expiration of the Build America Bond program are eligible for the federal tax subsidy.

EXCHANGE-TRADED PRODUCTS

ETPs include exchange traded funds (“ETFs”) registered under the 1940 Act; exchange traded commodity trusts; and exchange traded notes (“ETNs”). The Adviser may receive management or other fees from the ETPs (“Affiliated ETPs”) in which the Portfolios or Funds may invest, as well as a management fee for managing the Funds. It is possible that a conflict of interest among the Portfolios and Funds and Affiliated ETPs could affect how the Adviser fulfills its fiduciary duties to the Portfolios and Funds and the Affiliated ETPs. Because the amount of the investment management fees to be retained by the Adviser may differ depending upon the Affiliated ETPs in which a Portfolio or Fund invests, there is a conflict of interest for the Adviser in selecting the Affiliated ETP. In addition, the

12

Table of Contents

Adviser may have an incentive to take into account the effect on an Affiliated ETP in which a Portfolio or Fund may invest in determining whether, and under what circumstances, to purchase or sell shares in that Affiliated ETP. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Portfolios and Funds.

Each Portfolio may invest in new ETPs or ETPs that have not yet established a deep trading market at the time of investment. Shares of such ETPs may experience limited trading volume and less liquidity, in which case the “spread” (the difference between bid price and ask price) may be higher.

INVESTMENT COMPANIES

Each Portfolio may invest in the securities of other investment companies, including affiliated funds, money market funds and closed-end funds, subject to applicable limitations under Section 12(d)(1) of the 1940 Act. Each Fund invests substantially all of its assets in the corresponding Portfolio. Pursuant to Section 12(d)(1), a fund may invest in the securities of another investment company (the “acquired company”) provided that the fund, immediately after such purchase or acquisition, does not own in the aggregate: (i) more than 3% of the total outstanding voting stock of the acquired company; (ii) securities issued by the acquired company having an aggregate value in excess of 5% of the value of the total assets of the fund; (iii) securities issued by the acquired company and all other investment companies (other than Treasury stock of the fund) having an aggregate value in excess of 10% of the value of the total assets of the fund; or (iv) in the case of investment in a closed-end fund, more than 10% of the total outstanding voting stock of the acquired company. A fund may also invest in the securities of other investment companies if such securities are the only investment securities held by the fund, such as through a master-feeder arrangement. Each Fund currently pursues its respective investment objective through such an arrangement. To the extent allowed by law, regulation, a Fund’s investment restrictions and the Trust’s exemptive relief, a Fund may invest its assets in securities of investment companies that are affiliated funds and/or money market funds in excess of the limits discussed above.

To the extent a fund invests in and, thus, is a shareholder of, another investment company, the fund’s shareholders will indirectly bear the fund’s proportionate share of the fees and expenses paid by such other investment company, including advisory fees, in addition to both the management fees payable directly by the fund to the fund’s own investment adviser and the other expenses that the fund bears directly in connection with the fund’s own operations.

EXCHANGE-TRADED FUNDS

Each Portfolio may invest in other exchange-traded funds (including ETFs managed by the Adviser). ETFs may be structured as investment companies that are registered under the 1940 Act, typically as open-end funds or unit investment trusts. These ETFs are generally based on specific domestic and foreign market securities indices. An “index-based ETF” seeks to provide investment results that match the performance of an index by holding in its portfolio either the contents of the index or a representative sample of the securities in the index. An “enhanced ETF” seeks to provide investment results that match a positive or negative multiple of the performance of an underlying index. In seeking to provide such results, an ETF and, in particular, an enhanced ETF, may engage in short sales of securities included in the underlying index and may invest in derivatives instruments, such as equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Alternatively, ETFs may be structured as grantor trusts or other forms of pooled investment vehicles that are not registered or regulated under the 1940 Act. These ETFs typically hold commodities, precious metals, currency or other non-securities investments. ETFs, like mutual funds, have expenses associated with their operation, such as advisory and custody fees. When a fund invests in an ETF, in addition to directly bearing expenses associated with its own operations, including the brokerage costs associated with the purchase and sale of shares of the ETF, the fund will bear a pro rata portion of the ETF’s expenses. In addition, it may be more costly to own an ETF than to directly own the securities or other investments held by the ETF because of ETF expenses. The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities or other investments held by the ETF, although lack of liquidity in the market for the shares of an ETF could result in the ETF’s value being more volatile than the underlying securities or other investments.

EXCHANGE-TRADED NOTES

Each Portfolio may invest in exchange-traded notes. ETNs are debt obligations of investment banks which are traded on exchanges and the returns of which are linked to the performance of market indexes. In addition to trading ETNs on exchanges, investors may redeem ETNs directly with the issuer on a weekly basis, typically in a minimum amount of 50,000 units, or hold the ETNs until maturity. ETNs may be riskier than ordinary debt securities and may have no principal protection. A fund’s investment in an ETN may be influenced by many unpredictable factors, including highly volatile commodities prices, changes in supply and demand relationships, weather, agriculture, trade, changes in interest rates, and monetary and other governmental policies, action and inaction. Investing in ETNs is not equivalent to investing directly in index components or the relevant index itself. Because ETNs are debt securities, they possess credit risk; if the issuer has financial difficulties or goes bankrupt, the investor may not receive the return it was promised.

QUALIFIED PUBLICLY TRADED PARTNERSHIPS

Regulated investment companies are subject to favorable tax treatment under the Internal Revenue Code. To qualify as a regulated investment company, each Fund must derive at least 90% of its gross income for each taxable year from sources generating “qualifying income.” For these purposes, each Fund is generally expected to be treated as if it held its share of the corresponding Portfolio’s investments and realized its share of the corresponding Portfolio’s income and loss directly. Income derived from direct and certain indirect investments in commodities is not qualifying income. Thus, income from certain commodities-related investments may cause a Fund not to qualify as a regulated investment company. Each Portfolio may invest up to 25% of its total assets in one or more ETPs that are qualified publicly traded partnerships (“QPTPs”) and whose principal activities are the buying and selling of commodities or options, futures, or forwards with respect to commodities. Income from QPTPs is generally qualifying income. A QPTP is an entity that is treated as a partnership for federal income tax purposes, subject to certain requirements. If such an ETP fails to qualify as a QPTP, the income generated from the Portfolio’s investment in the ETP may not be qualifying income. The Portfolio will only invest in such an ETP if it intends to qualify as a QPTP, but there is no guarantee that each such ETP will be successful in qualifying as a QPTP. In addition, there is little regulatory guidance concerning the application of the rules governing qualification as a QPTP, and it is possible that future guidance may adversely affect the qualification of such ETPs as QPTPs. If a Fund fails to qualify as a regulated investment company, the Fund itself will be subject to tax, which will reduce returns to the Fund’s shareholders. Such a failure will also alter the treatment of distributions to the Fund’s shareholders.

U.S. REGISTERED SECURITIES OF FOREIGN ISSUERS

The Portfolios (except the Blackstone / GSO Senior loan Portfolio) may purchase publicly traded common stocks and preferred securities of foreign corporations. In addition, each Portfolio may invest in U.S. registered, dollar-denominated bonds of foreign corporations, governments, agencies and supra-national entities.

Investing in U.S. registered, dollar-denominated, securities issued by non-U.S. issuers involves some risks and considerations not typically associated with investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries, and potential restrictions of the flow of international capital. Foreign companies may be subject to less governmental regulation than U.S. issuers. Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

Investments in common stock of foreign corporations may also be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively “Depositary Receipts”). Depositary Receipts are receipts, typically issued by a bank or trust company, which evidence ownership of underlying securities issued by a foreign corporation. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a foreign issuer. For other Depositary Receipts, the depository may be a foreign or a U.S. entity, and the underlying securities may have a foreign or a U.S. issuer. Depositary Receipts will not necessarily be denominated in the same currency as their underlying securities. Generally, ADRs, in registered form, are designed for use in the U.S. securities market, and EDRs, in bearer form, are designated for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world. A Portfolio may invest in unsponsored Depositary Receipts. The issuers of unsponsored Depositary Receipts are not obligated to disclose material information in the United States, and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the Depositary Receipts.

REAL ESTATE INVESTMENT TRUSTS (“REITs”)

Each Portfolio may invest in REITs. REITs pool investor’s funds for investment primarily in income producing real estate or real estate loans or interests. A REIT is not taxed on income distributed to shareholders if it complies with several requirements relating to its organization, ownership, assets, and income and a requirement that it distribute to its shareholders at least 90% of its taxable income (other than net capital gains) for each taxable year. REITs can generally be classified as Equity REITs, Mortgage REITs and Hybrid REITs. Equity REITs, which invest the majority of their assets directly in real property, derive their income primarily from rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs, which invest the majority of their assets in real estate mortgages, derive their income primarily from interest payments. Hybrid REITs combine the characteristics of both Equity REITs and Mortgage REITs. A Portfolio will not invest in real estate directly, but only in securities issued by real estate companies. However, a Portfolio may be subject to risks similar to those associated with the direct ownership of real estate (in addition to securities markets risks). These include declines in the value of real estate, risks related to general and local economic conditions, dependency on management skill, heavy cash flow dependency, possible lack of availability of mortgage funds, overbuilding, extended vacancies of properties, increased competition, increases in property taxes and operating expenses, changes in zoning laws, losses due to costs resulting from the clean-up of environmental problems, liability to third parties for damages resulting from environmental problems, casualty or condemnation losses, limitations on rents, changes in neighborhood values, the appeal of properties to tenants and changes in interest rates. Investments in REITs may subject Portfolio shareholders to duplicate management and administrative fees.

14

Table of Contents

In addition to these risks, Equity REITs may be affected by changes in the value of the underlying property owned by the trusts, while Mortgage REITs may be affected by the quality of any credit extended. Further, Equity and Mortgage REITs are dependent upon management skills and generally may not be diversified. Equity and Mortgage REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, Equity and Mortgage REITs could possibly fail to qualify for the beneficial tax treatment available to REITs under the Internal Revenue Code, or to maintain their exemptions from registration under the 1940 Act. The above factors may also adversely affect a borrower’s or a lessee’s ability to meet its obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

NON-PRINCIPAL INVESTMENT STRATEGIES

LEVERAGING

While the Portfolios and Funds do not anticipate doing so, each Portfolio and Fund may borrow money in an amount greater than 5% of the value of their respective total assets. However, a Portfolio or Fund may not borrow money from a bank in an amount greater than 33  ¹ ⁄ ₃ % of the value of the Portfolio’s or Fund’s total assets. Borrowing for investment purposes is one form of leverage. Leveraging investments, by purchasing securities with borrowed money, is a speculative technique that increases investment risk, but also increases investment opportunity. Because substantially all of each Portfolio’s and Fund’s assets will fluctuate in value, whereas the interest obligations on borrowings may be fixed, the NAV of a Portfolio or Fund will increase more when such Portfolio’s or Fund’s portfolio assets increase in value and decrease more when the Portfolio’s or Fund’s portfolio assets decrease in value than would otherwise be the case. Moreover, interest costs on borrowings may fluctuate with changing market rates of interest and may partially offset or exceed the returns on the borrowed funds.

REPURCHASE AGREEMENTS

Each Portfolio may invest in repurchase agreements with commercial banks, brokers or dealers to generate income from its excess cash balances and to invest securities lending cash collateral. A repurchase agreement is an agreement under which a fund acquires a financial instrument ( e.g. , a security issued by the U.S. government or an agency thereof, a banker’s acceptance or a certificate of deposit) from a seller, subject to resale to the seller at an agreed upon price and date (normally, the next Business Day – as defined below). A repurchase agreement may be considered a loan collateralized by securities. The resale price reflects an agreed upon interest rate effective for the period the instrument is held by a fund and is unrelated to the interest rate on the underlying instrument.

In these repurchase agreement transactions, the securities acquired by a fund (including accrued interest earned thereon) must have a total value in excess of the value of the repurchase agreement and are held by the Custodian until repurchased. No more than an aggregate of 15% of a Portfolio’s net assets will be invested in illiquid securities, including repurchase agreements having maturities longer than seven days and securities subject to legal or contractual restrictions on resale, or for which there are no readily available market quotations.

The use of repurchase agreements involves certain risks. For example, if the other party to the agreement defaults on its obligation to repurchase the underlying security at a time when the value of the security has declined, a fund may incur a loss upon disposition of the security. If the other party to the agreement becomes insolvent and subject to liquidation or reorganization under the U.S. Bankruptcy Code or other laws, a court may determine that the underlying security is collateral for a loan by a fund not within the control of the fund and, therefore, the fund may not be able to substantiate its interest in the underlying security and may be deemed an unsecured creditor of the other party to the agreement.

REVERSE REPURCHASE AGREEMENTS

Each Portfolio may enter into reverse repurchase agreements, which involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. The securities purchased with the funds obtained from the agreement and securities collateralizing the agreement will have maturity dates no later than the repayment date. Generally the effect of such transactions is that a fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases a fund is able to keep some of the interest income associated with those securities. Such transactions are only advantageous if a fund has an opportunity to earn a greater rate of interest on the cash derived from these transactions than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available and a Portfolio intends to use the reverse repurchase technique only when the Adviser believes it will be advantageous to the Portfolio and, therefore, the Fund. The use of reverse repurchase agreements may exaggerate any interim increase or decrease in the value of a Portfolio’s and, therefore, a Fund’s assets. A Portfolio’s exposure to reverse repurchase agreements will be covered by securities having a value equal to or greater than such commitments. Under the 1940 Act, reverse repurchase agreements are considered borrowings. Although there is no limit on the percentage of fund assets that can be used in connection with reverse repurchase agreements, the Portfolios do not expect to engage, under normal circumstances, in reverse repurchase agreements with respect to more than 33  ¹ ⁄ ₃ % of their respective total assets.

RATINGS

An investment-grade rating means the security or issuer is rated investment-grade by Moody’s, S&P, Fitch, Inc., Dominion Bond Rating Service Limited, or another credit rating agency designated as a nationally recognized statistical rating organization by the SEC, or is unrated but considered to be of equivalent quality by the Adviser or applicable Sub-Adviser.

Subsequent to purchase by a Portfolio, a rated security may cease to be rated or its investment grade rating may be reduced below an investment grade rating. Securities rated lower than Baa3 by Moody’s or BBB- by S&P or Fitch are below investment grade quality and are obligations of issuers that are considered predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Such securities (“lower rated securities”) are commonly referred to as “junk bonds” and are subject to a substantial degree of credit risk. Lower rated securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) firms, which are generally less able than more financially stable firms to make scheduled payments of interest and principal. The risks posed by securities issued under such circumstances are substantial. Bonds rated below investment grade tend to be less marketable than higher-quality bonds because the market for them is less broad. The market for unrated bonds is even narrower. See “HIGH YIELD SECURITIES” above for more information relating to the risks associated with investing in lower rated securities.

SPECIAL CONSIDERATIONS AND RISKS

A discussion of the risks associated with an investment in each Fund is contained in the Prospectus. The discussion below supplements, and should be read in conjunction with, the Prospectus.
